Indicаte whether the fоllоwing stаtements аre true оr false. Vesicles for regulated exocytosis will not bud off the trans Golgi network until the cell receives the appropriate signal. [answer1] Often, the fusion of the secretory vesicles with the plasma membrane is stimulated by an increase in cytoplasmic [Ca2+]. [answer2] Secretory vesicles are transported directly from the ER to the plasma membrane, where they discharge their contents to the cell’s exterior. [answer3] The secretion of insulin is an example of constitutive secretion. [answer4]
Indicаte whether the fоllоwing stаtements аre true оr false. Most mitochondrial proteins are encoded in the mitochondrial genome. [answer1] Reovirus is activated when an outer shell viral protein is attacked by an intestinal protease. [answer2] An antibiotic that inhibits protein synthesis of a bacterium will likely inhibit protein synthesis in mitochondria. [answer3] The electrical potential of an uncharged molecule is always zero. [answer4] Reovirus cannot enter into the target cell via endocytosis because it is too large to fit inside an endocytic vesicle. [answer5] The nuclear envelop is thought to have evolved by invagination and pinching off from the plasma membrane of an ancient archaeon.[answer6]
